I am a PhD student in the Statistical Laboratory of the University of Cambridge. My research currently focusses on frequentist validity of Bayesian procedures. My supervisor is Richard Nickl.

## Background

**2011-2015** BA with MMath, University of Cambridge. My Part III essay, supervised by Richard Nickl and Jakob Söhl was on Nonparametric Drift Estimation from Low-Frequency Data.

**2015-present** PhD student in statistical theory, University of Cambridge

## Research

*[1]** *Nonparametric Bayesian posterior contraction rates for scalar diffusions with high-frequency data. *Bernoulli,* to appear.
